Fig. 4 is a section showing a slightly modified form of wird suitablefor use when bricks or bloc s are used.

lJig. 5 is a detail perspective view of a B modification showing adifferent manner designates a cross tie which may be of any usual orapproved construction, and for the tie shown, it will be understood thatthe ordinary metallic yokes commonly used in the construction ofunderground street railways may be substituted.

The tie may rest upon any suitable foundation, such as soil, ballast,concrete, etc., and in the present monolithic system of pav ingillustrated, thc tie is superimposed upon a concrete base 3 whichsupports the binder 4, and wearing surface 5 of asphalt, but it shouldbe understood that my invention is equally appropriate to pavementswherein the wearing surface is of concrete, bricks, blocks, etc.

The numeral 6 designates the rail of ordinary construction havingfillers7, of concrete or any suitable "material, and'in the present instance,the outer faces of the filler are straight, as indicated at 8,'so asunder no circumstances to 'form a lock between the rail. and filler, andthe adjacent portions of vthe pavement. Vhere the top portion. of therail, above the-Web -is narrower 40l than the base, the upper portion ofthe v,filler is extended so as to be in direct vertical linewith-thebase, and where the base of the rail. ,i snarrower than the topportion, ythe filler is extended at the bottom, so that 45, in allcases, -the'side surface of the fillers will be straight.

The numeral '8' designates a Ymetallic guard,.two of which. arepreferably einplyed, one on,v cachgsidc otthefraih adja- "S'Ocent tothe'. track. `They are ident-ical in form, and one of the. gi'iards on'-which lever side of the .raildesireth may be omitted,

but as before slated, it. is preferable to employ two guards as iii sucha case` obviously, 'the paven'iei'itioii bothsides'of the Jin thei'iia'in-., vertical, Ii-Qifi'oii'sf and tegral horizontal l-ior'tions'10,. and vare of considerable length, in practice being te-ii or morefeet long. for a purpose which.v

will presently become apparent.

horizontal portions 10 of the guard at siii able intervals are anchorimembers 11 proieefoo'r vided with eyes 12 which embrace reinforcingrods 13 which are embedded in the concrete base 3, uiid'serve the doublefunc tion of anchoring the guards and reinforcing the concrete und'consequently the paving, adjacent to the rails, and Ato'further 70reinforce the base, I preferably provide additional reinforcingrods 14which run. longitudinally of the rails, and are in sections sutlicientlylong to reinforce the con'- crete above the tie, or they may becontinuous, that is to say, only limited in length by the necessitieswhich characterize the easy or practical handlin of the rods. In theform shown' in igs. l and'-2, the guards serve as a boundary for thepavement, wherein the wearing surfacel and binder are brought entirelyup tothe rails, which is rendered entirely practical by. the position'of the parts shown, in that the viration of the rail is not in any Wayiinparted to the upper portion of the roadbed, the same' being entirelyindependent of the vertical movements of the rails, which is one of themost important features of the present invention. Where the pavement isof aI type other than monolithic these guards form a boundary for thebricks ad'acent to the rails.- v

eferringA back ,to the Figs. 1 ,and 4v, the numerals 26 `and '2'7designate filler-'backersarranged on opposite sides of the web oftheraili These are preferably slightly seated in the concrete filler'7, and-a-re"preferably formed of asphalt, or a material having yielding orowin'g characteristics. :Spaces or voids as indicated by 28, areleftbetween base and ball of the rail, at the top andbottom of thesemembers, so as to provide space into'which the material of said membersmay flow or expand, to correspondto any inward and outward movementjt'he rail fillers' may have. vThese membersfare subor blocksvstantially continuous and extend'iioi'l'thieeni tire length'of therails, and ofcourse correspond in length to" the filler. This arrange`mentA provides for' the contractionundfexpansion of` the rail fillersand the payel .f

ment adjacent thereto, so vas to maintain' a comparatively tight jointbetweenfthe-palr'ts at all times, but not sufficiently tight to preventthe independentvertical movement of the rail and parts carried thereby',whichas has been stated.l is one of the" objects of. the presentinvention.'

ln Fig; 4 a modification' is shown wherein' the guards are so shaped asto adaptthem 'to receive thebricks or blocks commonly used. instreetrailway construction."`-In this instance, vertical portions 15 oftheguards"- arecorisiderubly longer than' that shown in Depending from theouter edges ofit'lgf principal 'I `zontal portions o f the g'uard'ahownin Figs.

rods 13, as in the main figures.

Fig. 5 shows a modified form of guard,

which comprises a'plate 18, which extends l to the surface of theroadway, and downwardly toa point some distance above the cross tie 1,"`it being important that this plate sto Short of the tie, so as nottehave any of te vibrations f the tie incident to travel tobe communicatedto the plate, and `through it to the pavement. In thisform, l. provideIlaterally extending lugs 19 at intervals, having apertures 20therethrough to 4embrace the` rods 13, to keep the plate firmly tied` tothe paving base, and to insure its true vertical position relative tothe rail and filler. i

VIn Fi 6, is illustrated another form of anchor'or the guard plate 18.This' contemplates puiichinv or separating ii. lon tudinal section 21roui the plate and splitting it, as indicated at 22, which section isbent at theA point b at right angles to the plate, und then the splitends ofthe portion 2l are .bent in opposite directions to fornioppositeiy extending anchor arms 23 parvallel Vwith-the mainbody of theplate.

- 13 and 14 and by tyingthe guards to the In the construction shown, .itwill'be readily seen that by the provision of l'long guard platesfirmlyftied in the base, `a long 'durable wearing surface is formedadjacent to the rails and that the vconstruction is such that I can'provide a much heavier concrete base than is possible in' ordinaryconstruction, strengthening thev Wearing surface adjacent to the tracks,and .thus giving Vit structural strength at the points where needed,itbe-v ing well knownl that the usual lWearing surface has little or nostructural strength. A

`The strength of the concrete 3 is further greatly increased by thepresence of the rods rods 13, the ipards are prevented from having anyroc 'ng or lateral movement and their inner'faces, adjacent to therailand rail filler, arekept alwaysin true'vertical position.` y Theconcretebase is stopped in true vertical line with .the inner face ofthe vertical portions 9 ofthe guards', as indicate-,dat so thiitfrom thetop edge-'of the guard to the tie or support for the rail, there is atrue `vertical surface and the -rail filler and rail,

are entirelyiindependent of allfportions `of i the roadway abovethe tie,'so that the `vibrations of the rail, which 'are invariiii ble, u

and `cannot be' obviated are not transmitted,

in any` degree to the `street str iictureadja cent" tothe rai1s,lthuscompletely protecting the street and adding to. itsrdurability; ItWillbe further noted that in fthe con-v struction sho-wn in Figs. 1 and2, and in the construction shown in Fig'. 3,'the wearing the sainebefore suggested, teen feet Vin length, or really limited in. lengthonly by the condition incident to cona anchoring rods lis the and 2` Inthe kind of pavement illustrate d'in' r Fig.V 4, or one in which blocksor-bricks aref` surface and binder 4l adjacent to the rails, 65

'I ain aware that it is not broadly new toprovide a rail with guards having for their purpose the prevention otvibrations oi the rail being imparted to the pavement adj.ficcnl'- therails, butjso far as l ain aware., these have never `been of' practicalc onstifiiction` or operation, either because their'lorni `was"` suchthat in their use' they were `soinewh atl tied to the rail. andnaturallyl partake cfits` short as to virtually become 'the equivalentvmovement, or that they have been inadelso",

Thisis on account*of-'fiv the fact thatthe-pavement adjacen'ttof the ytrack is suiiciently reinforced forthis j' sort of pavement by the guardplates.
